FIELD OF THE INVENTION

[0001] The present invention relates to a modular living enclosure thatcan be assembled in an existing or new building and connected tobuilding services to support occupancy of a person therein.

BACKGROUND OF THE INVENTION

[0002] A modular security cell for confining a prisoner in an existingbuilding is described in U.S. Pat. No. 4,754,584. The cell is formed byassembling substantially identical flat wall and ceiling panels on theexisting floor of the building. Furniture and bathroom fixtures, such asa toilet and washbasin, are provided separately from the cell and mustbe placed into the cell as separate components.

[0003] An object of the present invention is to provide a modular livingenclosure to support occupancy by a person, such as for example aprisoner, for extended time such as days, months or years.

SUMMARY OF THE INVENTION

[0004] The present invention provides a modular living enclosure tosupport occupancy by a person wherein the living enclosure is assembledfrom multiple molded plastic enclosure sections in an existing or newbuilding and wherein one or more enclosure sections is/are molded toform certain integral features such as for example only bathroomfixtures and/or furniture features on the enclosure to permit occupancyby a person for extended time, such as days, months or years.

[0005] The present invention provides in one embodiment a modular livingenclosure comprising multiple enclosure sections that are assembled todefine an enclosure floor, four upright side walls, a top wall and dooropening when assembled. The enclosure sections preferably comprise ahard, abrasion resistant inner layer that defines the interior surfacesof the cell and preferably comprises ceramic particulates in a fireretardant synthetic resin. The inner layer is backed by a plurality offiber reinforced, particulate-filled synthetic resin layers to form awall thickness of the enclosure sections. One or more the layers behindthe hard inner layer can include a pigment to impart a color to thelayer(s) that is different from that of the inner layer to warn of anypenetration of the gel coat layer by a prisoner in the event theenclosure is used to house a prisoner. For example, the inner layer canhave a white color, while one or more fiber reinforced layers can beorange in color.

[0006] In another embodiment of the invention, one or more of theenclosure sections are molded to include features that form bathroomfixtures and/or furniture features in the living enclosure when theenclosure sections are assembled for use by a person during extendedtime. For example, a toilet fixture, washbasin fixture, shower, andfloor drain can be molded on one or more other enclosure sections andconnected to building water and sewer service lines. A bed surface,seating surface, a desk surface and other furniture features can bemolded on one or more of the enclosure sections. In an illustrativeembodiment, the washbasin and a shower are supplied with water frombuilding water service lines. The enclosure may include an electricalwater heater to provide hot water to the washbasin and shower. Thedrains of the washbasin and floor drain are communicated to a commonsump chamber on the enclosure. The sump chamber is pumped to a buildingsewer service line. The toilet is connected to a waste disposal device,such as a garbage disposal, that comminutes waste that then is pumped toa building sewer line. A lighting fixture, ventilation fan, monitoringcamera as well as temperature control and emergency fire/smoke sprinklerprotection devices can be provided on the enclosure and connected to abuilding electrical service line. A programmable computer control unitcan be used to control supply of water to the bathroom fixtures andsupply of electrical power to electrical devices on the enclosure.

[0007] In a still further embodiment of the invention, the moldedenclosure sections include cooperating L-shaped flanges by which thesections are assembled. When joined together, the L-shaped flanges forman upstanding surface on which a fascia panel can be fastened to coverone or more sides of the assembled living enclosure or adjacent livingenclosures in the event several living enclosures are arranged in a row.

The invention is not limited to use as a prisonerliving enclosure (prisoner cell) and can be used as a living enclosurein emergency situations such as fire, floods and the like, as asupplemental living enclosure to supplement an existing housingfacility, such as a hospital, dormitory, motel, barracks, home and inany other situation where a further living enclosure is needed.

[0033] An illustrative modular living enclosure 10 is shown in FIGS. 1-4as comprising a plurality of molded plastic enclosure sections 20 a, 20b, 20 c, 20 d, 20 e, 20 f that are assembled to define an enclosurefloor F, four upright side walls S1, S2, S3, S4, and a top wall T and adoor opening DO when assembled. The floor and portions of the side wallsare formed by enclosure sections 20 a, 20 b. The remainder of the sidewalls are formed by sections 20 c, 20 d. The closed top wall of theenclosure 10 is formed by top sections 20 e, 20 f.

[0034] The sections 20 a, 20 b include molded-on feet 20 af, 20 bf thatare adapted to rest on the floor FL of an existing or new building B,FIG. 21, and to be attached to floor FL by suitable fasteners or othermeans. For example, the horizontal flange portion of the L-shaped feet20 af and 20 bf include drilled holes to receive a respective screw SCor other fastener by which the enclosure 10 is fixed to the floor of thebuilding B. The floor FL of the building typically will be concrete suchthat the fastener FL is selected of the type for use in fastening toconcrete. Other building floor materials may be encountered, and thefasteners FL will be selected accordingly. Support legs LL can bepositioned under the outside corners of sections 20 a, 20 b on thebuilding floor FL for further support of the enclosure 10. The supportlegs can be hinged to the enclosure sections or otherwise attachedthereon, or they may separate support legs positioned between theunderside of the enclosure and the building floor.

[0035] The section 20 a is illustrated as being molded to include anintegral bed surface 31, seat or stool surface 32, and shelf surface 33for use by the occupant of the enclosure. The section 20 b isillustrated as being molded to include an integral bathroom washbasinfixture 34, toilet 35, floor drain 37, and a shower head (not shown) onthe section 20 f above the floor drain 37 to this same end. The floor ofthe enclosure is designed to slope toward the floor drain 37 so that theinside surfaces of the assembled enclosure 10 can be sprayed orotherwise washed down with water and/or cleaning solution to clean themand drained through the floor drain 37.

[0036] The washbasin, toilet, floor drain, and shower are adapted to beconnected to a building water service line and a building sewer line asdescribed below with respect to FIGS. 5-20. Similarly, electricallighting fixtures and other electrical devices (not shown in FIGS. 1-4)provided on the enclosure as described below with respect to FIGS. 5-20are adapted to be connected to building electrical service. FIGS. 1-4are offered merely to illustrate simplified views of one embodiment ofthe enclosure sections 20 a-20 f preparatory to describing a preferredembodiment of the enclosure sections pursuant to the invention. FIG. 21illustrates several living enclosures 10 disposed on floor FL inbuilding B having roof RF. The building B can be a warehouse, gymnasium,garage, or any other new or exiting building in which the enclosures canbe positioned.

[0037] The sections 20 a, 20 b are molded to include integral molded-onL-shaped flanges 21 a, 21 b and flat flanges 21 aa, 21 bb, FIG. 3, thatare abutted during assembly and fastened together as illustrated inFIGS. 1 and 2.

The flanges 21 a, 21 b can include drilledholes 31, FIG. 3, in registry with one another and through whichfasteners (not shown but similar to fasteners 38 described below) suchas bolts can be inserted and secured with nuts to join the flanges 21 a,21 b together. When assembled together, the flanges 21 a, 21 b locatedon the floor regions of the sections 20 a, 20 b collectively form anintermediate foot between feet 20 af, 20 bf, FIG. 1, for resting on thefloor FL of the building. The flanges 21 aa, 21 bb on the rear side wallregion include drilled holes and are similarly joined together byfasteners 38. The flanges 21 a, 21 b; 21 aa, 21 bb as well as the othermolded-on flanges described below on the enclosure sectionsalternatively, or in addition, may be clamped or otherwise fastenedtogether. When assembled at the flanges 21 a, 21 b; 21 aa, 21 bb, thesections 20 a, 20 b include a parting line PL1 on the floor F and rearside wall S4 of the enclosure 10. The floor F of the sections 20 a, 20 bcan be molded to include a non-slip interior surface, such as a raiseddiamond pattern (not shown) on the floor F or any other surface featuresand/or textures, to provide secure footing.

[0038] The sections 20 a, 20 b also include molded-on curvilinearforwardly facing flanges 22 a, 22 b on the front side wall S3. Theflanges 22 a, 22 b each include horizontal and upright regions connectedby a curved region to form a lower portion of the door opening DO.

[0039] The sections 20 a, 20 b also include molded-on, laterallyextending horizontal flanges 23 a, 23 b that face upwardly. Theseflanges are adapted to receive the enclosure sections 20 c, 20 dthereon.

[0040] For example, the sections 20 c, 20 d include horizontaldownwardly facing, laterally extending flanges 24 a, 24 b that rest onupwardly facing flanges 23 a, 23 b. The flanges 23 a, 23 b; 24 a, 24 bextend about the periphery of the enclosure, except for door opening DO,and include drilled holes through which fasteners 38 such as bolts 38 acan be inserted and secured with nuts 38 b as described above.

[0041] The sections 20 c, 20 d also include molded-on forwardlyextending, upright flanges 25 a, 25 b on the front side wall S3. Theflanges 25 a, 25 b form an intermediate portion of the door opening DO.The sections 20 c, 20 d also include molded-on rearwardly extending,upright flanges 26 a, 26 b on the rear side walls. The flanges 26 a, 26b include drilled holes through which fasteners 38 can be inserted andsecured with nuts 38 b as described above. When assembled, the sections20 a, 20 b; 20 c, 20 d include therebetween a horizontal parting linePL2 on the lateral and rear side walls S1, S2, S4 and an upright partingline PL3 on the rear side wall S4 of the enclosure 10.

[0042] The sections 20 c, 20 d also include molded on horizontal flanges27 a, 27 b that face upwardly. These flanges are adapted to receive theenclosure sections 20 e, 20 f thereon.

[0043] For example, the sections 20 e, 20 f include downwardly facing,horizontal flanges 28 a, 28 b that rest on upwardly facing flanges 27 a,27 b. The flanges 27 a, 27 b; 28 a, 28 b extend about the periphery ofthe enclosure, except for door opening DO, and include drilled holes inregistry with one another and through which fasteners 38 such as bolts38 a can be inserted and secured with nuts 38 b as described above.

[0044] The sections 20 e, 20 f also include molded-on forwardlyextending downwardly facing, horizontal flanges 29 a, 29 b on the frontside wall S3. The flanges 29 a, 29 b form an upper portion of the dooropening DO.

[0045] The sections 20 e, 20 f also include molded-on upwardlyextending, upright flanges 30 a, 30 b on the top wall T. The flanges 30a, 30 b include registered drilled holes through which fasteners 38 canbe inserted and secured as described above. When assembled, the sections20 c, 20 d; 20 e, 20 f include therebetween a horizontal parting linePL4 on the lateral and rear side walls S1, S2, S4 and a parting line PL5on the top wall T of the enclosure 10.

[0046] When the enclosure sections 20 a-20 f are assembled as described,living enclosure 10 is formed having enclosure floor F, four uprightside walls S1, S2, S3, S4, a top wall T and a door opening DO. A door(not shown) can be hinged or otherwise fastened on the enclosure toclose off the opening DO. The door is not shown in FIGS. 1-4 forconvenience is illustrating interior features of the enclosure 10. Thedoor can be hinged on the upright jamb surfaces of the flanges 22 a, 22b and 25 a, 25 b defining the opening DO. The door can be provided witha suitable shape to close off the opening DO and a conventional lock orlatch mechanism (not shown) to cooperate with a lock or latch mounted onthe enclosure 10.

[0047] Although not shown in FIGS. 1-4, a decorative fascia panel can beattached to the side walls S1, S2, S3, S4 to hide the joined flanges 23a, 23 b; 24 a, 24 b; etc. and exterior surfaces of the sections 20 a-20f from view. The flanges 23 a, 23 b; 24 a, 24 b; 27 a, 27 b; 28 a, 28 b;29 a, 29 b can be molded to have an L-shape as illustrated in FIG. 10Ato provide an upright surface to which an upright decorative fasciapanel can be readily attached as described below with respect to theembodiment of FIGS. 5-20. The fascia panel P can be molded to includelayers R1-R4 described below, or it can comprise any suitable panelmaterial.

[0048] The enclosure sections 20 a-20 f each are molded to have a wall Whaving an inner abrasion resistant, ceramic particulate-filled gel coatlayer R1 defining an interior surface of said enclosure, FIGS. 1-2, whenthe enclosure sections are assembled. Each wall W also is molded toinclude a plurality of fiber reinforced, particulate-filled resin layersbehind the hard inner layer R1.

[0049] For example, each enclosure section 20 a-20 f can be made byspraying a suitable plastic material on a respective master mold (notshown) having a configuration to produce each particular enclosuresection 20 a-20 f. For purposes of illustration, each enclosure sectioncan be made by spraying on its master mold in a first step, a firstrelatively hard, abrasion resistant filled plastic, fire retardant resininner layer R1 (FIG. 10B) using a filled resin system #1 as described inTable #1 through a commercially available two-chamber spray gun (e.g.PRO Series spray gun from manufacturer, Venus Gusmer Inc.) having astatic mixer of sufficient length to thoroughly mix filled resin system#1 with a methyl ethyl ketone peroxide catalyst (e.g. High Point 90 byWitco Corporation) as it is sprayed on the surface of the master mold.This mixture (i.e. resin system #1 and catalyst) is then allowed topolymerize or cure to a relatively high hardness; namely, 65 to 75Barcol Hardness. The filled resin system #1 (step 1) is sprayed to forminner hard gel coat layer R1 to have a nominal thickness of about 0.030inch. Although spraying is the preferred method of application, filledresin system #1 can be hand catalyzed, mixed, and then brushed on orpoured on the surface of the mold and allowed to polymerized or cure.

[0050] A second filled, plastic fire retardant resin layer R2 (FIG. 10B)is sprayed on the inner hard layer R1 after it cures using a filledresin system #2 as described in Table #2 through a commerciallyavailable two-chamber spray gun (e.g. PRO Series spray gun frommanufacturer, Venus Gusmer Inc.) having a static mixer of sufficientlength to thoroughly mix filled resin system #2 with a methyl ethylketone peroxide catalyst (e.g. High Point 90 by Witco Corporation) as itis sprayed on the surface of the mold. This mixture (i.e. resin system#2 and catalyst) is then allowed to polymerize or cure to a hardness of50-60 Barcol Hardness. The filled resin system #2 (step 2) is sprayed toform a filled intermediate resin layer R2 to have a nominal thickness ofabout 0.030 inch. Although spraying is the preferred method ofapplication, filled resin system #2 can be hand catalyzed, mixed, andthen brushed on or poured on the surface of the mold and allowed topolymerized or cure.

[0051] After the aforementioned mixture forming intermediate filledresin layer R2 has cured, a step 3 involves spraying another plasticlayer R3 behind the second layer R2. The third layer R3 is formed byspraying the resin system #2 as described above on layer R2 immediatelyfollowed by spraying filled resin system #3 as described in Table 3 andchopped fiberglass fibers through a two-chamber gun of the typedescribed above having a static mixer of sufficient length to thoroughlymix filled resin system #3 with the above catalyst as it is sprayed.This spray gun is also be equipped with a conventional chopper headavailable from the above manufacturer to cut the fiberglass gun rovinginto 1″ lengths. Both the chopped fibers and the filled resin system #3are simultaneously sprayed behind the filled resin system #2 at apreferred ratio of 70% by weight of resin and 30% by weight of choppedfiberglass. The mixture is then rolled out and allowed to polymerize orcure to form fiber reinforced filled resin layer R3. Step #3 describedabove is repeated three more times to form fiber reinforced filled resinlayers R4, R5, R6. Each fiber reinforced filled resin layer R3, R4, R5,R6 has a nominal thickness of about 0.090 inch. The total thickness ofthe wall W of each cell section is about 0.42-0.43 inch, although otherwall thicknesses can used in practice of the invention. A cross-sectionthrough the wall W of a cell section is shown in FIG. 10B.

[0052] The door described above for closing off opening DO is molded inthe same manner as described for sections 20 a-20 f. The door willcomprise inner hard layer R1 with additional layers R2-R5 behind theinner layer R1 as described above for the enclosure sections 20 a-20 f,and an additional hard outer layer R1 described above.

Table I Resin System #1

[0053] Filled resin system #1 is available as KZ Ceramic Gelcoat fromCeramic Technologies Corporation of Rowley, Iowa and is described inU.S. Pat. No. 5,688,851, the teachings of which are incorporated hereinby reference. An illustrative system comprises a mixture consisting of25% by weight of a commercially available fire retardant, syntheticplastic resin selected from the polyester or vinyl ester group,(although other thermosetting or other plastic resins may be foundsuitable), 72% by weight of tabular alumina particles, 2% by weight ofwollastonite based product (filler particles) as described in U.S. Pat.No. 4,568,604 and sold under the trademark “KZ6” by Ceramic TechnologiesCorporation of Rowley Iowa, and 1% by weight Titanium Dioxide. It willbe understood by those skilled in the art that the above mixture hasbeen found to be preferred but that deviation from the percents listedor the filler or other constituents used is within the scope of thisinvention.

Table 2 Resin System #2

[0054] Filled resin system #2 comprises a mixture consisting of 48% byweight of a commercially available fire retardant, synthetic plasticresin selected from the polyester or vinyl ester group, (although otherthermosetting or other plastic resins may be found suitable), 48% byweight of wollastonite based product (filler particles) as described inU.S. Pat. No. 4,568,604 and sold under the trademark “KZ6” by CeramicTechnologies Corporation of Rowley Iowa, 2% by weight of the mineralTalc, 1% by weight of a hollow microsphere sold under the trademark“Dualite” by Pierce and Stevens Corporation of Buffalo N.Y., and 1% byweight Titanium Dioxide. It will be understood by those skilled in theart that the above mixture has been found to be preferred but thatdeviation from the percents listed or the filler or other constituentsused is within the scope of this invention.

Table 3 Resin System #3

[0055] Resin system #2 comprises a mixture consisting of 71% by weightof a synthetic plastic resin selected from the polyester or vinyl estergroup, (although other thermosetting plastic resins may be foundsuitable), 25% by weight of wollastonite based product (fillerparticles) as described in U.S. Pat. No. 4,568,604 and sold under thetrademark “KZ9” by Ceramic Technologies Corporation of Rowley Iowa, 2%by weight of the mineral Talc, 1% by weight of a hollow microsphere soldunder the trademark “Dualite” by Pierce and Stevens Corporation ofBuffalo N.Y., and 1% by weight Titanium Dioxide. An optional pigmentsuch as “Moly-Orange” pigment available from HK Research Corporation canbe substituted for titanium dioxide in the mixture in the same amount(1% by weight) to impart an orange color to layers R5, R6 as describedbelow. It will be understood by those skilled in the art that the abovemixture has been found to be preferred but that deviation from thepercents listed or the filler or other constituents used is within thescope of this invention.

[0056] It will be noted that the filled resin system #1, #2 and #3 eachcontain the catalyst described above so that the layers forming theenclosure section walls W cure on the mold without the need for heatingto this end.

[0057] The resin systems #1, #2 without chopped fibers and resin system#3 with chopped fiberglass fibers as described above are sprayed on aone piece, open-bottom master mold (not shown) shaped to correspond to arespective enclosure section 20 a-20 f. The master mold is fabricated ofthe same material layers as described above that are sprayed on arespective master wooden pattern. Each fabricated master mold isprovided with a draft angle of 1 degree (or other suitable draft angle)to permit removal of each sprayed, cured enclosure section 20 a-20 fvertically from its master mold out of the open bottom of the mold.

[0058] If the enclosure 10 is to be used to house a prisoner (prisonercell), one or more the layers R2-R5 behind the inner hard layer R1 caninclude a pigment to impart a color to one or more of the layer(s) R2-R5that is different from that of the inner layer R1 to warn of anypenetration of the inner hard layer R1 by a prisoner. For example only,the layers R1-R4 can have a white color, while an orange (or othercolor) pigment can be added to resin system #3 used to form the fiberreinforced layers R5, R6 such that those layers have a bright orangecolor. For example, the above pigment known as “Moly-Orange” pigmentavailable from HK Research Corporation can be substituted for titaniumdioxide in the resin system #3 in an amount of 1% by weight to impart anorange color to layers R5, R6 if the enclosure is to be used as aprisoner cell.

[0059] Should a prisoner attempt to escape from the enclosure 10 byabrading and/or cutting away the interior surface, the orange color oflayers R5, R6 will visually appear and provide a visual alert of suchprisoner activity. The high hardness of the inner gel coat layer R1 willmake abrasion and/or cutting of the interior of the enclosure difficultand time consuming by the prisoner.

[0060] Referring to FIGS. 5-20, a preferred living enclosure for use inhousing a prisoner is shown for purposes of illustration and notlimitation. In FIGS. 5-20, similar reference numerals primed are used todesignate similar features of FIGS. 1-4. Each enclosure section 20 a′-20i′ is made by spraying suitable plastic materials described above on arespective master mold of each enclosure section to form the enclosureconfiguration having wall W′ including the above inner hard layer R1forming the interior surfaces of the assembled enclosure backed bylayers R2, R3, R4, R5, and R6.

[0061] The enclosure 10′ includes a plurality of molded plasticenclosure sections 20 a′, 20 b′, 20 c′, 20 d′, 20 e′, 20 f′, 20 g′, 20h′, and 20 i′ that are assembled to define an enclosure floor F′, fourupright side walls S1′, S2′, S3′, S4′, a top wall T′ and a door openingDO′ when assembled. The floor and portions of the side walls are formedby three lower enclosure sections 20 a′, 20 b′ and 20 g′, FIG. 7, ratherthan two sections 20 a, 20 b of FIGS. 1-4. The three sections 20 a′, 20b′, 20 g′ are shown best in FIG. 7 and define parting lines PLlA′ andPLlB′ in the floor and side walls of the enclosure. It is apparent thatsections 20 a′, 20 b′ are oriented parallel to one another and the frontand rear side walls S3′, S4′ of the enclosure 10′ and perpendicular tosection 20 g′. The remainder of the side walls are formed by foursections 20 c′, 20 d′, 20 h′, 20 i′ stacked atop sections 20 a′, 20 b′,20 g′, respectively. The sections 20 c′, 20 d′, 20 h′, 20 i′ defineupright parting lines (e.g. PL3′) between one another and horizontalparting lines (e.g. PL2′, PL4′) with the enclosure sections 20 a′, 20b′, 20 g′ and 20 e′, 20 f′. The closed top wall of the enclosure 10′ isformed by top sections 20 e′, 20 f′. The top sections 20 e′, 20 f′ areoriented parallel to the front and rear side walls S3′, S4′ of theenclosure 10′ rather than perpendicular thereto as in FIGS. 1-4.

[0062] The sections 20 a′-20 i′ are connected together by molded-onintegral L-shaped flanges 121 a′, 121 b′, FIG. 10A, rather than thehorizontal flanges 23 a, 23 b; 24 a, 24 b; etc. of FIGS. 1-4. TheL-shaped flanges of adjacent enclosure sections nest in one another andare fastened together by fasteners 38′ comprising bolt 38 a′ and nut 38b′. A silicone or other sealant (not shown) can be applied between theflanges before assembly. The nested flanges 121 a′, 121 b′ define anupright surface 38 c″ on which decorative fascia panel P′, FIG. 12, canbe mounted for purposes described above. In FIGS. 5-20, all of theL-shaped flanges on sections 20 a′-20 g′ are designated 121 a′, 121 b′for convenience.

[0063] Sections 20 a′, 20 b′, 20 g′ can include molded-on feet (notshown) similar to feet 20 af, 20 bf (FIGS. 1-4) that are adapted to reston floor FL of building B and to be attached thereto by suitablefasteners or other means as described above. Support legs (not shown)similar to legs LL of FIGS. 1-4 can be placed under section 20 g′ andother sections for stability.

[0064] The sections 20 a′, 20 b′ are illustrated as being molded toinclude an integral bed surface 31′, seat or stool surface 32′ for useby the occupant of the enclosure. Section 20 c′ is illustrated as beingmolded to form the shelf surface 33′ and desk surface 36′. The section20 g′ is illustrated as being molded to include an integral bathroomwashbasin fixture 34′, toilet 35′, shower 41′, floor drain 37′ to thissame end. Section 20 h′ is illustrated as being molded to includeshelves 39′. Section 20 f′ is illustrated as being molded to include ashower 41′ formed by integral shower dome or head 41 a′ having drilledholes 41 b′ for water discharge.
